I'll get a better look at it tonight after work, but I gave it a quick look, and didn't see anything that stood out right way.

Check the plug gaps, these engines can be sensitive to it, I was chasing something similar on my own mustang.

the tune file looks good so nothing wrong with the tune that will cause that , change plugs.
